Abstract
Management of Neuroendocrine liver metastases (NELM) is challenging. The presence of NELM worsens survival outcome and almost 10% of all liver metastases are neuroendocrine in origin. There is no firm consensus on the optimal treatment strategy for NELM. A systematic search of the PubMed database was performed from 1995-2010, to collate the current evidence and formulate a sound management algorithm. There are 22 case series with a total of 793 patients who had undergone surgery for NELM. The overall survival ranges from 46-86% at 5 years, 35-79% at 10 years, and the median survival ranges from 52-123 months. After successful cytoreductive surgery, the mean duration of symptom reduction is between 16-26 months, and the 5-year recurrence/progression rate ranges from 59-76%. Five studies evaluated the efficacy of a combination cytoreductive strategy reporting survival rate of ranging from 83% at 3 years to 50% at 10 years. To date, there is no level 1 evidence comparing surgery versus other liver-directed treatment options for NELM. An aggressive surgical approach, including combination with additional liver-directed procedures is recommended as it leads to long-term survival, significant long-term palliation, and a good quality of life. A multidisciplinary approach should be established as the platform for decision making.

Abstract
AIM The incidence, patterns of care and survival were determined in patients with stage IV colorectal cancer (CRC) in a population-based series. METHOD Computer records for patients diagnosed with stage IV CRC diagnosed from 1 January 1995 to 31 December 2007 were retrieved from the Rotterdam Cancer Registry. Surgical resection of the primary tumour, chemotherapy use, hepatic surgery and survival were evaluated according to year of diagnosis, age, gender and primary tumour site. RESULTS In the southwestern part of the Netherlands, 19 014 new patients with CRC were diagnosed and synchronous metastatic disease was found in 3482 (18%). This proportion increased during the study period, from 16% to 21%. Surgical resection of the primary tumour was performed in approximately 50% of the patients and did not change over time. Postoperative 30-day mortality was 8%. Chemotherapy use increased from 18% in the first period to 56% in the latest period. Liver surgery increased from 4% in the first period to 10% in the latest period. Median survival increased from 7 months to 12 months and 2-year survival increased from 14% to 28%. Two-year survival declined with increasing age and was significantly worse for right-sided tumours (14%). CONCLUSION Survival of patients with stage IV CRC has improved over time and this is probably a result of the increased use of chemotherapy and the increased numbers of patients who underwent hepatic surgery.

Abstract
BACKGROUND Although hepatectomy for metastatic colorectal cancer (mCRC) offers prolonged survival in up to 40% of people, recurrence rates are high, approaching 70%. Many patients experience recurrent disease in the liver after initial hepatectomy. We examined our experience with repeat hepatectomy for mCRC. METHODS After Institutional Review Board approval, we reviewed the records of all patients at a single institution who underwent hepatectomy for mCRC. Repeat hepatectomy was defined as partial liver resection any time after the initial hepatectomy for recurrent mCRC. We estimated time to recurrence and survival by using the Kaplan-Meier method and compared outcomes between groups by using the log-rank test. RESULTS From 1998 to 2008, 405 patients underwent hepatectomy for mCRC, and 215 (53%) experienced disease recurrence at a median of 13 months. Of 150 patients with liver-only or liver-predominant recurrence, 52 (35%) underwent repeat hepatectomy. The median time to recurrence after repeat hepatectomy was 10 months, and median overall survival was 19 months. There was one (1.9%) perioperative death, and there were 14 (27%) major complications. The median overall survival in the repeat hepatectomy group from the time of recurrence after initial hepatectomy was 22 months, compared with 15 months in the 98 patients with liver recurrence who were not selected for repeat hepatectomy (P=0.02). CONCLUSIONS Repeat hepatectomy for mCRC is feasible in highly selected patients, with acceptable perioperative morbidity and mortality. Although repeat hepatectomy should be considered, recurrence rates are high. Although the initial hepatectomy for mCRC is potentially curative, recurrence of metastatic disease in the liver is unlikely to be cured.

Abstract
Hepatic resection is the procedure of choice for curative treatment of colorectal liver metastases (CLM). Objectives of surgical strategy are low intraoperative blood loss, short liver ischemic times and minor postoperative morbidity and mortality. Blood loss is an independent predictor of mortality and compromises, in common with postoperative complications, long-term outcome after hepatectomy for CLM. The type of liver resection has no impact on the outcome of patients with CLM; wedge resections are not inferior to anatomical resections in terms of tumor clearance, pattern of recurrence or survival. Despite the lack of proof of survival benefit, routine lymphadenectomy has been advocated, allowing the detection of microscopic lymph node metastases and with prognostic value. In experienced hands, minimally invasive liver surgery is safe with acceptable morbidity and mortality and oncological results comparable to open hepatic surgery, but with reduced blood loss and earlier recovery. The European Colorectal Metastases Treatment Group recommended treating up front with chemotherapy for patients with both resectable and unresectable CLM. However, neoadjuvant chemotherapy can induce damage to the remnant liver, dependent on the number of chemotherapy cycles. Therefore, in our opinion, preoperative chemotherapy should be reserved for patients whose CLM are marginally resectable or unresectable. A meta analysis of randomized trials dealing with perioperative chemotherapy for the treatment of resectable CLM demonstrated a benefit of systemic chemotherapy but did not answer the question of whether a neoadjuvant or adjuvant approach should be preferred. Analysis of the literature demonstrates that the results of specialized centers cannot be attained in the reality of comprehensive patient care. Reasons behind the commonly poorer results seen in cancer networks as compared with literature-based data are, on the one hand, geographical disparities in access to specialized surgical and medical care. On the other hand, a selection bias in the reports of the literature may be assumed. Studies of surgical resection for CLM derive almost exclusively from case series generally drawn from large academic centers where patient selection or surgical expertise is superior to what is found in many communities. Therefore, we may conclude that the comprehensive propagation of the standards outlined in this paper constitutes a major task in the near future to reduce the variations in survival of patients with CLM.

Abstract
The management of colorectal liver metastases has been improved these last years. The efficacy of chemotherapy regimens and targeted therapies has led to a better prognosis. It has also allowed the resection of metastases initially unresectable. In this setting, the pathologist plays a major role. He is involved in the gross examination, in order to perform an adequate sampling of the lesions. He is also involved at the morphological level, for the assessment of the pathological response, which is now recognized as a prognostic factor and a marker of sensitivity or resistance to a given treatment. Moreover, the determination of predictive markers of response or resistance to induction treatments will constitute a supplementary and major challenge for the pathologist.

Abstract
Half of patients with colorectal cancer have liver metastasis during their illness. Surgical resection of metastases represents the only curative treatment with prolonged survival in more than 50 % of patients. The aim of liver resection is complete excision of the lesions with histological negative margins while preserving sufficient functional liver parenchyma. In patients with diffuse liver disease, the radiofrequency ablation of metastases may be associated with surgical resection. The use of portal vein remobilization and neoadjuvant chemotherapy can also increase the number of patients for curative treatment. Despite this progress, from 50 to 60 % of patients relapse after complete resection of MHCCR. Surgical treatment of recurrent aggressive and effective chemotherapy allows the prolonged survival of these patients. The modern treatment of liver metastasis of colorectal cancers can be envisaged as part of a multidisciplinary approach to increase the number of patients for curative treatment.

Abstract
Synchronous or metachronous colorectal liver metastases (CLMs), although being the expression of systemic disease, allow a curative approach for about 25-35% of patients. Patients presenting with CLMs should receive a multimodal management in order to increase the number of patients undergoing R0 surgery and to decrease the rate of recurrence. Postoperative and/or pre-operative systemic chemotherapy shows beneficial impact regarding progression-free and overall survival, without increasing postoperative complication rates. Concerning the complex definition of resectability and the number of patients with 'borderline' resectable CLMs, pre-operative chemotherapy plays an important role in both the improvement of prognosis and 'conversion' to resectability. Duration of chemotherapy in the peri-operative setting should not exceed 6 months. Current data do not recommend the use of locally applied chemotherapy using hepatic artery infusion after resection of CLMs. Liver surgery has made several advances extending resectability to a larger group of patients and decreasing local hepatic recurrence. Moreover, locally ablative procedures such as radiofrequency and selective internal radiation therapy have joined the armamentarium in the case of positive resection margins or unresectable disease. Future research will help in defining treatment regimens and approaches in this setting.

Abstract
BACKGROUND The outcome after a repeat hepatectomy for recurrent colorectal liver metastases (CLM) is not well defined. The present study examined the morbidity, mortality and long-term survivals after a repeat hepatectomy for recurrent CLM. METHODS Data on patients who underwent surgery for recurrent CLM between 1993 and 2009 were retrospectively evaluated. Patients who underwent radiofrequency ablation at the time of first treatment or at recurrence of CLM were excluded. RESULTS Forty-three patients underwent a repeat hepatectomy for recurrent CLM. At the time of recurrence, patients had a median of 1 (1-3) lesions and the median tumour size was 2 (0.5-8.7) cm. The post-operative morbidity and mortality rates were 12% and 0%, respectively. After a median follow-up of 33 months from a repeat hepatectomy, 5-year overall and progression-free survival rates were 73% and 22%, respectively. Using multivariate analysis, the largest initial CLM ≥5 cm and positive surgical margins at initial resection were independently associated with a worse survival after surgery for recurrent CLM. Positive surgical margins at repeat hepatectomy were a predictive factor for an increased risk of further recurrence. DISCUSSION A repeat hepatectomy for recurrent CLM was associated with excellent survival, low morbidity and no mortality. Surgeon-controlled variables, including margin-negative resection at first and repeat hepatectomy, contribute to good oncological outcome.

Abstract
BACKGROUND Data from patients with colorectal liver metastases (CRLM) who received neoadjuvant chemotherapy before resection were reviewed and evaluated to see whether neoadjuvant chemotherapy influences the predictive outcome of R1 resections (margin is 0 mm) in patients with CRLM. METHODS Between January 2000 and December 2008, all consecutive patients undergoing liver resection for CRLM were analyzed. Patients were divided into those who did and did not receive neoadjuvant chemotherapy. The outcome after R0 (tumor-free margin >0 mm) and R1 (tumor-free margin 0 mm) resection was compared. RESULTS A total of 264 were eligible for analysis. Median follow-up was 34 months. Patients without chemotherapy showed a significant difference in median disease-free survival (DFS) after R0 or R1 resection: 17 [95% confidence interval (CI) 10-24] months versus 8 (95% CI 4-12) months (P < 0.001), whereas in patients with neoadjuvant chemotherapy the difference in DFS between R0 and R1 resection was not significant: 18 (95% CI 10-26) months versus 9 (95% CI 0-20) months (P = 0.303). Patients without chemotherapy showed a significant difference in median overall survival (OS) after R0 or R1 resection: 53 (95% CI 40-66) months versus 30 (95% CI 13-47) months (P < 0.001). In patients with neoadjuvant chemotherapy, the median OS showed no significant difference: 65 (95% CI 39-92) months for the R0 group versus the R1 group, in whom the median OS was not reached (P = 0.645). CONCLUSIONS In patients treated with neoadjuvant chemotherapy, R1 resection was of no predictive value for DFS and OS.

Abstract
BACKGROUND Patient outcomes following resection of colorectal liver metastases (CLM) after second-line chemotherapy regimen is unknown. METHODS From August 1998 to June 2009, data from 1099 patients with CLM were collected prospectively. We retrospectively analyzed outcomes of patients who underwent resection of CLM after second-line (2 or more) chemotherapy regimens. RESULTS Sixty patients underwent resection of CLM after 2 or more chemotherapy regimens. Patients had advanced CLM (mean number of CLM ± standard deviation, 4 ± 3.5; mean maximum size of CLM, 5 ± 3.2 cm) and had received 17 ± 8 cycles of preoperative chemotherapy. In 54 (90%) patients, the switch from the first regimen to another regimen was motivated by tumor progression or suboptimal radiographic response. All patients received irinotecan or oxaliplatin, and the majority (42/60 [70%]) received a monoclonal antibody (bevacizumab or cetuximab) as part of the last preoperative regimen. Postoperative morbidity and mortality rates were 33% and 3%, respectively. At a median follow-up of 32 months, 1-year, 3-year, and 5-year overall survival rates were 83%, 41%, and 22%, respectively. Median chemotherapy-free survival after resection or completion of additional chemotherapy administered after resection was 9 months (95% confidence interval, 4-14 months). Synchronous (vs metachronous) CLM and minor (vs major) pathologic response were independently associated with worse survival. CONCLUSIONS Resection of CLM after a second-line chemotherapy regimen was found to be safe and was associated with a modest hope for definitive cure. This approach represents a viable option in patients with advanced CLM.

Abstract
BACKGROUND Systemic chemotherapy is the mainstay of treatment for metastatic breast cancer with the role of surgery being strictly limited for palliation of metastatic complications or locoregional relapse. An increasing number of studies examining the role of therapeutic hepatic metastasectomy show encouraging survival results. A systematic review was undertaken to define its safety, efficacy and to identify prognostic factors associated with survival. METHODS Electronic search of the MEDLINE and PubMed databases (January 2000-January 2011) to identify studies reporting outcomes of hepatectomy for breast cancer liver metastases (BCLM) with hepatectomy was undertaken. Two reviewers independently appraised each study using a predetermined protocol. Safety and clinical efficacy was synthesised through a narrative review with full tabulation of results of all included studies. RESULTS Nineteen studies were examined. This comprised of 553 patients. Hepatectomy for BCLM was performed at a rate of 1.8 (range, 0.7-7.7) cases per year in reported series. The median time to liver metastases occurred at a median of 40 (range, 23-77) months. The median mortality and complication rate were 0% (range, 0-6%) and 21% (range, 0-44%), respectively. The median overall survival was 40 (range, 15-74) months and median 5-year survival rate was 40% (range, 21-80%). Potential prognostic factors associated with a poorer overall survival include a positive liver surgical margin and hormone refractory disease. CONCLUSION Hepatectomy is rarely performed for BCLM but the studies described in this review indicate consistent results with superior 5-year survival for selected patients with isolated liver metastases and in those with well controlled minimal extrahepatic disease. To evaluate its efficacy and control for selection bias, a randomised trial of standard chemotherapy with or without hepatectomy for BCLM is warranted.

Abstract
BACKGROUND An extended left hepatectomy is a complex hepatic resection often performed for large tumours in close relationship to major hilar structures. Operative outcomes of this resection for colorectal liver metastases (CLM) remain unclear. The aim of the present study was to assess short- and long-term outcome for patients with CLM after an extended left hepatectomy. METHODS A retrospective analysis of consecutive patients undergoing an extended left hepatectomy for CLM in a large, single-centre cohort between January 1990 and January 2006 was performed. RESULTS Thirty-one patients (3.9%) from a consecutive series of 802 patients who had undergone hepatic resection were identified as having met the definition of an extended left hepatectomy and were included for further analysis. Maximum tumour size was more than 60 mm in 15 patients, with a median size of 67.5 mm for the total group (range: 20 to 160 mm). Twenty-six patients presented with initially unresectable metastases, related to large tumour size in 11 patients and to a close relation with major vascular structures in six patients. Preoperative chemotherapy was administered to 29 patients. Combined vascular resection was performed in five patients. The mortality rate at 90 days was zero and post-operative morbidity occurred in 17 patients. R0 and R1 resections were performed in 17 and 11 patients, respectively. Three- and 5-year overall survival was 38% and 27%, respectively. Disease-free survival was 9% and 4% at 3 and 5 years. Morbidity did not differ between patients with and without a caudate lobectomy (9 of 17 patients vs. 8 of 14 patients, respectively) (P= 0.815). CONCLUSIONS An extended left hepatectomy for CLM can provide significant long-term survival. However, morbidity is increased in this complex procedure. A caudate lobectomy does not impact surgical outcome.

Abstract
Liver surgery has been known to cure metastatic colorectal cancer in a small proportion of patients. However, advances in procedural technique and chemotherapy now allow more patients to have safe, potentially curative surgery. Here we review surgery for unresectable colorectal liver metastases using an expert multidisciplinary approach. With multidisciplinary management of patients with effective chemotherapy that can downstage metastases, more patients with previously inoperable disease can benefit from surgery. Portal vein embolization results in hypertrophy of the future liver remnant; on occasions, combining embolization with staged liver resection permits potentially curative surgery for patients previously unable to survive resection. However, increasing use of chemotherapy has raised awareness of potential hepatotoxicity and other deleterious effects of cytotoxic agents. Prolonged prehepatectomy chemotherapy therefore can reduce resectability even using a 2-stage procedure. Suitable timing of surgery for unresectable liver metastases during chemotherapy is critical. Because of advances in chemotherapy, colorectal cancer, like ovarian cancer, can now show survival benefit from maximum surgical debulking. Benefit from such maximum hepatic debulking surgery for metastatic colorectal disease is uncertain, but likely. Surgery in isolation may be approaching technical limits, but is now likely to help more patients because of the success of complementary strategies, particularly newer chemotherapy and targeted therapy. Expert individualized multidisciplinary treatment planning and problem-solving is essential.

Abstract
Colorectal cancer is the third most commonly diagnosed cancer with approximately half of the patients developing liver metastases during the course of their disease. Modern multimodal therapies have improved the overall survival. Liver resection remains the most important modality in the treatment of colorectal liver metastases. The evolution of the criteria for resectability has resulted in more patients being offered a hepatectomy. This is further augmented with the utilization of adjuncts to liver resection, including portal vein embolization and local ablative techniques. Two-stage hepatectomy is also being used to increase resectability. Overall survival is improved by the deployment of new chemotherapeutic agents and the use of combination chemotherapy. Neoadjuvant chemotherapy is a promising development in the treatment of colorectal liver metastases. Patients with colorectal liver metastases can achieve long-term survival. A multidisciplinary approach is essential in the management of these patients.

Abstract
BACKGROUND Up to 5 per cent of liver resections for colorectal cancer metastases involve the caudate lobe, with cancer-involved resection margins of over 50 per cent being reported following caudate lobe resection. METHODS Outcomes of consecutive liver resections for colorectal metastases involving the caudate lobe between 1996 and 2009 were reviewed retrospectively, and compared with those after liver surgery without caudate resection. RESULTS Twenty-five patients underwent caudate and 432 non-caudate liver resection. Caudate resection was commonly performed as part of extended resection. There were no differences in operative complications (24 versus 21·1 per cent; P = 0·727) or blood loss (median 300 versus 250 ml; P = 0·234). The operating time was longer for caudate resection (median 283 versus 227 min; P = 0·024). Tumour size was larger in the caudate group (median 40 versus 27 mm; P = 0·018). Resection margins were smaller when the caudate lobe was involved by tumour, than in resections including tumour-free caudate or non-caudate resection; however, there was no difference in the proportion of completely excised tumours between caudate and non-caudate resections (96 versus 96·1 per cent; P = 0·990). One-year overall survival rates were 90 and 89·3 per cent respectively (P = 0·960), with 1-year recurrence-free survival rates of 62 and 71·2 per cent (P = 0·340). CONCLUSION Caudate lobe surgery for colorectal cancer liver metastases does not increase the incidence of resection margin involvement, although when the caudate lobe contains metastases the margins are significantly closer than in other resections.

Abstract
BACKGROUND The increased use of neoadjuvant chemotherapy and minimally invasive therapies for recurrence in patients with colorectal liver metastases (CLM) makes a surgical strategy to save as much liver volume as possible pivotal. In this study, we determined the difference in morbidity and mortality and the patterns of recurrence and survival in patients with CLM treated with anatomical (AR) and nonanatomical liver resection (NAR). METHODS From January 2000 to June 2008, patients with CLM who underwent a resection were included and divided into two groups: patients who underwent AR, and patients who underwent NAR. Patients who underwent simultaneous radiofrequency ablation in addition to surgery and patients with extrahepatic metastasis were excluded. Patient, tumor, and treatment data, as well as disease-free and overall survival (OS) were compared. RESULTS Eighty-eight patients (44%) received AR and 113 patients (56%) underwent NAR. NAR were performed for significant smaller metastases (3 vs. 4 cm, P < 0.001). The Clinical Risk Score did not differ between the groups. After NAR, patients received significantly less blood transfusions (20% vs. 36%, P = 0.012), and the hospital stay was significantly shorter (7 vs. 8 days, P < 0.001). There were no significant differences in complications, positive resection margins, or recurrence. For the total study group, estimated 5-year disease-free and OS was 31 and 44%, respectively, with no difference between the groups. CONCLUSIONS Our study resulted in no significant difference in morbidity, mortality, recurrence rate, or survival according to resection type. NAR can be used as a save procedure to preserve liver parenchyma.

Abstract
Colorectal cancer (CRC) is one of the cancer models and most of the carcinogenic steps are presently well understood. Therefore, successful preventive measures are currently used in medical practice. However, CRC is still an important public health problem as it is the third most common cancer and the fourth most frequent cause of cancer death worldwide. Nowadays, pathologic stage is a unique and well-recognized prognostic indicator, however, more accurate indicators of the biologic behavior of CRC are expected to improve the specificity of medical treatment. Angiogenesis plays an important role in the growth and progression of cancer but its role as a prognostic factor is still controversial. Probably the most important clinical implication of tumor angiogenesis is the development of anti-angiogenic therapy. The goal of this review is to critically evaluate the role of angiogenic markers, assessed by either endoglin-related microvessel density or expression of vascular endothelial growth factor family members in the CRC setting and discuss the role of these angiogenic markers in anti-angiogenic therapies.

Effectiveness and cost-effectiveness of peri-operative versus post-operative chemotherapy for resectable colorectal liver metastases. Eur J Cancer 2011; 47:2291-8.

Abstract
BACKGROUND The role of neo-adjuvant chemotherapy prior to hepatectomy in patients with resectable colorectal liver metastases is currently a matter of debate. The aim of the present study was to analyse life-expectancy, quality adjusted life-expectancy and cost-effectiveness of the two chemotherapeutic strategies. METHODS A Markov decision model was developed, on the basis of parameters derived from an extensive literature search of the last ten years, to compare outcomes of peri-operative versus post-operative chemotherapy. RESULTS Life-expectancy observed for peri-operative chemotherapy was 54.56months and 52.62months with post-operative chemotherapy only; the quality-adjusted life-expectancy with peri-operative chemotherapy was 39.33 quality-adjusted life-months (QALMs) and 37.84 QALMs with post-operative chemotherapy. Peri-operative chemotherapy results in an increase in total costs of 1180€ over ten years and in an incremental cost-effectiveness ratio (ICER) of 791.9€/QALM. The model was more sensitive to the expected 3-year recurrence-free survival (RFS) and cost of hepatic resection: with respect to an expected 3-year RFS⩽25% the peri-operative approach was more cost-effective than post-operative strategy but differences in average cost-effectiveness were small. The relationship between ICER and cost of hepatic resection was inverse because the higher the cost of hepatic resection, the higher the cost saving due to patients becoming unresectable during neo-adjuvant therapy. CONCLUSIONS In the treatment of resectable colorectal liver metastases, the addition of neo-adjuvant chemotherapy could be cost-effective because it makes it possible to avoid hepatic resection in patients who do not respond to the neo-adjuvant approach; however, the life-expectancy of the two strategies is very similar.

Abstract
BACKGROUND Only 10-25% of patients presenting with colorectal liver metastases (CRLM) are amenable to hepatic resection. By combining resection and ablation, the number of patients eligible for surgery can be expanded. We sought to determine the efficacy of combined resection and ablation for CRLM. METHODS Between 1984 and 2009, 1,425 patients who underwent surgery for CRLM were queried from an international multi-institutional database. Of these, 125 patients underwent resection combined with ablation as the primary mode of treatment. RESULTS Patients presented with a median of six lesions. The median number of lesions resected was 4; the median number of lesions ablated was 1. At last follow-up, 84 patients (67%) recurred with a median disease-free interval of 15 months. While total number of lesions treated (hazard ratio (HR) = 1.47, p = 0.23) and number of lesions resected (HR = 1.18, p = 0.43) did not impact risk of intrahepatic recurrence, the number of lesions ablated did (HR = 1.36, p = 0.05). Overall 5-year survival was 30%. Survival was not influenced by the number of lesions resected or ablated (both p > 0.05). CONCLUSION Combined resection and ablation is associated with long-term-survival in a subset of patients; however, recurrence is common. The number of lesions ablated increases risk of intrahepatic recurrence but does not impact overall survival.

Abstract
BACKGROUND Perioperative chemotherapy improves outcome in resectable colorectal liver-only metastasis (CLM). This study aimed to evaluate perioperative CAPOX (capecitabine-oxaliplatin) plus bevacizumab in patients with poor-risk CLM not selected for upfront resection. PATIENTS AND METHODS Poor-risk CLM was defined as follows: more than four metastases, diameter >5 cm, R0 resection unlikely, inadequate viable liver function if undergoing upfront resection, inability to retain liver vascular supply, or synchronous colorectal primary presentation. Patients underwent baseline computed tomography, magnetic resonance imaging, and/or positron emission tomography (PET) for staging and received neoadjuvant CAPOX plus bevacizumab, with resectability assessed every four cycles. Primary end point was radiological objective response rate (ORR). RESULTS Forty-six patients were recruited, of which 91% underwent PET to ensure metastases confined to liver. Following neoadjuvant CAPOX plus bevacizumab, the ORR was 78% (95% confidence interval 63% to 89%). This allowed 12 of 30 (40%) patients with initial nonsynchronous unresectable CLM to be converted to resectability. In addition, 10 of 15 (67%) patients with synchronous resectable CLM underwent liver resection, with four additional patients being observed alone due to excellent response to neoadjuvant therapy. No grade 3-4 perioperative complications were seen. CONCLUSION Neoadjuvant CAPOX plus bevacizumab resulted in a high response rate for patients with CLMs with poor-risk features not selected for upfront resection and converted 40% of patients to resectability.

Abstract
AIMS Here we reassess anticipated inability to obtain a microscopically clear surgical margin as an absolute contraindication to surgery for colorectal liver metastases in view of improvements in treatment modalities adjunctive to surgery. METHODS We retrospectively analysed 310 patients treated at our institution to estimate the survival benefit from R1 hepatectomy performed to remove liver metastases from colorectal cancer. RESULTS Considering all 310 patients evaluated, the R1 resection group (positive margin; n = 55) showed a lower disease-free rate (P < 0.01) and worse overall survival (P < 0.01) than the R0 resection group (negative margin; n = 255). When patients were divided according to initial resectability, similar differences in disease-free rate and overall survival (P = 0.03) between R1 (n = 19) and R0 (n = 182) were observed in patients whose metastases were resectable. However, superior impact of R0 resection (n = 73) compared to R1 resection (n = 36) on disease-free rate (P = 0.44) and overall survival (P = 0.50) was not confirmed in patients with initially unresectable or marginally resectable metastases, especially those with a favourable response to prehepatectomy chemotherapy. CONCLUSIONS A predicted positive surgical margin after resection no longer should be an absolute contraindication to surgery for aggressive or advanced liver metastases.

Abstract
In the treatment of metastatic colorectal cancer, the subset of patients with liver-only metastases shows the greatest promise for prolonged survival and cure. Advances in surgery and medical treatment have encouraged multimodality treatment strategies and therefore require a true multidisciplinary approach. The current standard of care includes peri-operative chemotherapy and surgery. The new era of biologically targeted therapy requires an in-depth look at the possible efficacy and risks of adding these agents to the treatment protocol.

Abstract
PURPOSE A previous meta-analysis study demonstrated that bleeding and the duration of the hospital stay following laparoscopic hepatectomy (Lap) were significantly smaller and shorter, respectively, than for patients undergoing an open approach (Op). The aim of the present study was to re-evaluate perioperative variables and adverse outcomes in patients undergoing Lap versus (vs) Op after 2000. METHODS A PubMed and Ovid Medline search identified clinical studies that compared the outcomes of Lap vs Op patients after 2000. A meta-analysis and power analysis were performed. RESULTS Operative time was not significantly different between the two approaches (95% confidence interval [CI]: -0.063 to 0.992). Patient bleeding in the Lap group was significantly lower than in the Op group (95% CI: -1.027 to -0.390). Complications with Lap patients were significantly less frequent (95% CI: 0.231-0.642), and the duration of the hospital stay for Lap patients was significantly shorter (95% CI: -0.950 to -0.530) than for Op patients. Only one paper presented 80% power with 0.05 α-errors in all four outcomes, whereas four studies did not have sufficient statistical power. CONCLUSIONS The clinical benefits of Lap include a smaller incidence of complications and a shorter duration of hospital stay at the current time. Several studies had too few cases to sufficiently evaluate these factors, although other studies were appropriately analyzed.

Abstract
BACKGROUND Systemic chemotherapy (CTx) is increasingly used before surgery for colorectal liver metastases (CRC-LM). However, CTx may cause liver injury like steatosis, steatohepatitis, and sinusoidal injury which may be associated with postoperative morbidity. Some recent data have even shown an increased mortality in patients with CTx-associated steatohepatitis. We, therefore, analyzed our recent experience with potential hepatic injury and its association with CTx and morbidity in patients undergoing surgery for CRC-LM. METHODS From 2001 to 2007, 179 patients underwent primary liver resection for CRC-LM. Sufficient non-tumorous liver parenchyma could be re-evaluated for this study in 102 patients. In these 102 patients (66% male, median age 62 years, median BMI 26, 8% diabetics (IDDM)), liver injury was classified using established criteria for steatosis and sinusoidal dilatation (SD) and then compared with preoperative CTx and postoperative outcome. Fifty-eight percent of the operations were (extended) hemihepatectomies (ExtRes), 42% segmental or wedge resections (LimRes). Before resection, 66% had received CTx (33% FU-based (FU), 19% oxaliplatin-based (Oxa), 12% irinotecan-based (Iri), and 3% Oxa+Iri). The interval between CTx and surgery was always ≥4 weeks. RESULTS Mortality was 3/102 (2.9%). Any complication occurred in 48%, hepatic insufficiency in 5.9%, and liver-related complications in 24%. Hepatic steatosis >20% was found in 37% (half of them with steatosis >50%). BMI correlated with the frequency of steatosis. Steatosis >20% was more frequent in patients with preoperative chemotherapy but did not depend on the chemotherapy regimen. No relevant risk factor for grades 2 and 3 SD was found. The specific use of Oxa or Iri did not significantly correlate with hepatic injury. Neither a CTx per se nor the different CTx regimens nor the extent of hepatic injury showed any negative influence on mortality, complication rates, or hepatic insufficiency. Patients with IDDM had a higher mortality (25% vs 1% without IDDM; p<0.02), increased complication rate (75% vs 46%; p=0.11), a higher rate of hepatic insufficiency (25% vs 4%; p<0.02), and more liver related complications (50% vs 21%; p=0.06). Patients undergoing ExtRes had a higher overall (p<0.01) and liver-related (p=0.05) complication rate compared to LimRes. None of the 34 patients with preoperative Oxa or Iri died or developed hepatic insufficiency. CONCLUSIONS In our experience, hepatic injury (steatosis) was influenced by BMI and by preoperative CTx. Neither preoperative CTx nor liver injury increased perioperative morbidity. Patients with IDDM were at a rather high perioperative risk.

Abstract
The evolution of chemotherapeutic regimens that include targeted molecular agents has resulted in a breakthrough in the management of advanced colorectal liver metastasis (CLM), improving the progression-free survival after liver resection, and rendering initially unresectable liver tumors resectable, with reported resection rates ranging from 13% to 51%. In addition, the criteria used for selecting patients for hepatectomy have been expanding because of advances in surgical techniques and improvements in chemotherapy. However, the increasing use of chemotherapy has raised concern about potential hepatotoxicities such as steatosis, chemotherapy-associated steatohepatitis, and sinusoidal obstruction syndrome, and their deleterious effects on postoperative outcome. The present review focuses on the advantages and disadvantages of chemotherapy, strategies for the prevention and diagnosis of chemotherapy-associated liver injury, and the adoption of more aggressive surgical approaches, which have changed the traditional paradigm for CLM.

Abstract
Introduction: Metastatic disease to the liver in colorectal cancer is a common entity that may present synchronously or metachronously. While increasing surgical experience has improved survival outcomes, some evidence suggest that synchronous lesions should be managed differently. This review aims to update current literature on differences between the outcomes and management of synchronous and metachronous disease. Materials and Methods: Systematic review of MEDLINE database up till November 2008. Results: Discrete differences in tumour biology have been identified in separate studies. Twenty-one articles comparing outcomes were reviewed. Definitions of metachronicity varied from anytime after primary tumour evaluation to 1 year after surgery for primary tumour. Most studies reported that synchronous lesions were associated with poorer survival rates (8% to 16% reduction over 5 years). Sixteen articles comparing combined vs staged resections for synchronous tumour showed comparable morbidity and mortality. Benefits over staged resections included shorter hospital stays and earlier initiation of chemotherapy. Suitability for combined resection depended on patient age and constitution, primary tumour characteristics, size and the number of liver metastases, and the extent of liver involvement. Conclusions: Surgery remains the only treatment option that offers a chance of long-term survival for patients amenable to curative resection. Synchronicity suggests more aggressive disease although a unifying theory for biological differences explaining the disparity in tumour behaviour has not been found. Combined resection of primary tumour and synchronous metastases is a viable option pending careful patient selection and institutional experience. Given the current evidence, management of synchronous and metachronous colorectal liver metastases needs to be individualised to the needs of each patient.

Abstract
BACKGROUND This study assessed the feasibility and outcomes of combined colorectal and hepatic resection as the first step of two-stage hepatectomy in patients with bilobar synchronous colorectal liver metastases. METHODS All patients with bilobar synchronous colorectal liver metastases who were considered for two-stage hepatectomy, combining resection of the primary tumour with the first stage of hepatectomy, between 2000 and 2008 were selected from a prospectively collected database at two institutions. Data were analysed retrospectively on an intention-to-treat basis. RESULTS Thirty-three patients were studied. Twenty patients received neoadjuvant chemotherapy. Combined colorectal resection and clearance of left-sided liver metastases was the first-stage procedure in all but one patient, in whom right clearance was performed. In 17 patients right portal vein ligation was undertaken at the same time. No patient died. Two patients had anastomotic leakage. Interval chemotherapy was given to 25 patients, five of whom also had percutaneous portal vein embolization. Twenty-five patients had the second-stage hepatectomy, but not eight patients with disease progression. There was one postoperative death after the second stage, and eight patients experienced morbidity. Median follow-up from the first stage was 28.7 months. Overall and disease-free survival rates for patients who completed the procedure were 80 and 44 per cent respectively at 3 years, and 48 and 22 per cent at 5 years. CONCLUSION In patients with bilobar synchronous colorectal liver metastases who are candidates for two-stage hepatectomy, combined resection of the primary tumour and first-stage hepatectomy reduces the number of procedures, optimizes chemotherapy administration and may improve outcome.

Abstract
CONTEXT Colorectal cancer is the leading cause of morbidity and death among gastrointestinal tumors and ranks fourth after lung, breast, and ovarian cancers. Despite a continuous refinement of the T (tumor), N (node), and M (metastasis) staging system to express disease extent and define prognosis, and eventually to guide treatment, the outcome of patients with colorectal cancer may vary considerably even within the same tumor stage. Therefore, the need for new factors, either morphologic or molecular, that could more precisely stratify patients into different risk categories is clearly warranted. OBJECTIVES To present the state of the art with regard to the colorectal cancer staging system and to discuss confusing and/or challenging issues, including the assessment of peritoneal membrane involvement, vascular invasion, tumor deposits, and pathologic tumor response to neoadjuvant chemoradiotherapy. DATA SOURCES Literature review of relevant articles indexed in PubMed (US National Library of Medicine) and primary material from the authors' institutions. CONCLUSIONS Two emerging needs exist for the TNM system, namely, further stratification of patients with the same tumor stage and incorporation of nonanatomic factors, the latter including molecular and treatment factors. The identification and classification of morphologic features encountered in the pathologic examination of colorectal cancer specimens may be difficult and a source of subjective variability. Enhanced pathologic analysis, agreed-upon standard protocols, and standardization should improve the completeness and accuracy of pathology reports.

Abstract
OBJECTIVE To evaluate the results of surgical therapy for intrahepatic cholangiocarcinoma (ICC), the incidence and the management of recurrence, and to analyze the change in approach during 2 different periods. DESIGN Retrospective study. PATIENTS AND METHODS Patient and tumor characteristics, and overall and disease-free survival were analyzed in a series of 72 consecutive patients who underwent hepatic resection for ICC. Several factors likely to influence survival after resection were evaluated. Patients were divided into 2 groups according to the year of operation (before and after 1999). Management of recurrence and survival after recurrence were also analyzed. RESULTS The 3- and 5-year overall survival rates were 62% and 48%, whereas the 3- and 5-year disease-free survival rates were 30% and 25%, respectively. The median survival time was 57.1 months. Patient and histologic characteristics before and after 1999 were similar. Survival was significantly better among patients operated after 1999, who were node-negative, did not receive blood transfusion, and underwent adjuvant chemotherapy. The overall recurrence rates before and after 1999 were comparable (66.6% and 50%, P = 0.49). The most frequent site of recurrence was the liver. A significantly large number of patients received treatment for recurrence after 1999 (81.5%) compared with the first period (8.3%). The overall 3-year survival rate after recurrence was 46%. After 1999, there was a significant improvement in 3-year survival after recurrence (56%) compared with patients operated before 1999 (0%, P = 0.004); the median survival time from the diagnosis of recurrence increased from 20 months to 66 months in the second group. CONCLUSIONS Although recurrence rate represents a frequent problem in ICC, an aggressive approach to recurrence can significantly prolong survival.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma is rare, but its incidence is rapidly increasing in developed countries. Early detection and surgical extirpation offer the only hope for cure. Given the rarity of intrahepatic cholangiocarcinoma, there is limited knowledge regarding its natural history, clinicopathological characteristics, or outcomes following surgery. The primary aim of the current study is to report overall survival and recurrence-free survival outcomes following resection of intrahepatic cholangiocarcinoma. The secondary aim is to evaluate the impact of prognostic variables on outcomes. METHODS Between November 1990 and November 2009, 88 patients were evaluated for their suitability for potentially curative surgery; of these, 40 patients underwent potentially curative surgery. These patients are the principal subjects of the current analysis. Patients were assessed at monthly intervals for the first 3 months and then at six monthly intervals after treatment. Recurrence-free survival and overall survival were determined; 17 clinicopathological and treatment-related factors associated with recurrence-free survival and overall survival were evaluated through univariate and multivariate analyses. RESULTS No patient was lost to follow-up. The median follow-up was 31 months (range = 0-142 months). The median recurrence-free survival and overall survival after resection were 21 and 33 months, respectively. The 5-year survival rate was 28%. Four factors were associated with overall survival: carbohydrate antigen 19.9 (p = 0.020), clinical stage (p = 0.018), histological grade (p = 0.020), and lymph node metastases (p = 0.003). Two factors were associated with recurrence-free survival: carbohydrate antigen 19.9 (p = 0.002) and margin status (p = 0.002). CONCLUSION Hepatic resection is an efficacious treatment for intrahepatic cholangiocarcinoma. Clincopathological factors can predict outcome and should be used in the preoperative assessment of operability.

Abstract
About 50% of colorectal cancer patients develop liver metastasis, and liver resection is considered the only curative therapy. However, the rate of recurrence is high, which contributes to poor prognosis. Since surgical resection coverage has increased because of improved hepatectomy including portal vein embolization, tumors shrink because of the effectiveness of recent chemotherapy, such as FOLFOX and FOLFIRI, and it has become possible for many patients whose cancer was judged unresectable before to undergo resection. Improvement of new anticancer drugs such as molecularly targeted biologics is greatly changing therapeutic systems of metastatic colorectal cancer, and it is time for us to innovate stage IV therapy. In this report, we will review new treatment strategies for metastatic liver cancer from colorectal cancer, clinical trials of new anticancer drugs for liver metastasis, surgery and ablation as local therapy, and further clarify complex therapeutic systems for metastatic liver tumors from colorectal cancer.

Abstract
In this review the surgery of colorectal liver metastases is discussed. It has long been known that liver surgery can cure metastatic colorectal cancer although in only a small proportion of the population with the disease. However with better understanding of the natural history of the condition and advances in technique more patients can have safe, potentially curative surgery. The multidiscipline management of patients with effective chemotherapy has led to more patients benefiting from surgery after reducing the size of the metastases and allowing operation on patients who were previously inoperable. Chemotherapy also improves at least the medium-term outcome in those who are operable at the outset. Minimally invasive techniques have been developed so that major hepatectomy may be accomplished in up to half of such cases with a very short hospital stay and limited interference with quality of life. Lastly, using portal vein embolisation to cause hypertrophy of the future liver remnant and on occasions combining it with staged liver resection allows potentially curative surgery on patients who previously could not have survived resection. These developments have led to more patients being cured of advanced colorectal cancer.

Abstract
Surgical and oncological treatment of liver metastases of CRC has made a significant progress in the last twenty years. Although chemotherapy has developed enormously, only successfully resected (R0) patients may hope a long-term survival. The almost 60% recurrence rate after resection is a significant challenge. Authors review patients data operated at the Surgical Department of Uzsoki Teaching Hospital between 1995 and 2008 with hepatic metastases of colorectal origin. Oncological and surgical principles are summarized in the sight of the recent literature review and authors own experience with repeat hepatic resection. Recent literature data demonstrate--which is confirmed by our experience--that R0 resection of recurrent hepatic metastases provides similar overall 5 year survival rate than that of patients who underwent a single resection only. In the case of recurrent CLM, the oncoteam should prepare a surgically resectable situation.

Abstract
BACKGROUND Optimal margin width is uncertain because of conflicting results from recent studies using overall survival as the end-point. After recurrence, re-resection and aggressive chemotherapy heavily affect survival time; the potential confounding effect of such factors has not been investigated. Use of recurrence-free survival (RFS) may overcome this limitation. The aim of this study is to evaluate the impact of width of resection margin on RFS and site of recurrence after hepatic resection for colorectal metastases (CRM). METHODS From a prospectively maintained institutional database (1/1999-12/2007) we identified 314 patients undergone hepatectomy for CRM (1/1999-12/2007) with detailed pathologic analysis of the surgical margin and complete follow-up imaging studies documenting disease status and site of recurrence, which was categorized as: resection margin (M(arg)), other intra-hepatic ((other)IH), lung (L) or other extra-hepatic ((other)EH). Recurrence-free estimation was the survival end-point. RESULTS Median follow-up was 56.5 months. Two hundred and fifteen patients (68.8%) recurred at 288 sites after a mean of 15.5 months. A positive resection margin was associated with an increased risk of M(arg) recurrence (P < 0.001). The presence of >or=2 metastases was the only factor increasing the risk of positive margins (P < 0.05). The width of the negative resection margin (>or=1 cm versus >1 cm) was not a prognostic factor of worse RFS (30.2% versus 37.3%, P = 0.6). Node status of the primary tumour, and size and number of CRM were independent predictors of RFS. CONCLUSIONS Tumour biology and not the width of the negative resection margin affect RFS.

Abstract
BACKGROUND During the last two decades, resection of colorectal liver metastases (CLM) in selected patients has become the standard of care, with 5-year survival rates of 25-58%. Although a substantial number of actual 5-year survivors are reported after resection, 5-year survival rates may be inadequate to evaluate surgical outcomes because a significant number of patients experience a recurrence at some point. OBJECTIVES This study aimed to analyse longterm results and prognostic factors in liver resection for CLM in patients with complete 10-year follow-up data. METHODS A total of 369 patients who underwent liver resection for CLM between 1985 and 1998 were identified from a bi-institutional database. Postoperative deaths and patients with extrahepatic disease were excluded. Clinicopathological prognostic factors were analysed using univariate and multivariate analyses. RESULTS The sample included 309 consecutive patients with complete 10-year follow-up data. Five- and 10-year overall survival rates were 32% and 23%, respectively. Overall, 93% of recurrences occurred within the first 5 years of follow-up, but 11% of patients who were disease-free at 5 years developed later recurrence. Multivariate analysis demonstrated four independent negative prognostic factors for survival: more than three metastases; a positive surgical margin; tumour size >5 cm, and a clinical risk score >2. CONCLUSIONS Five-year survival rates are not adequate to evaluate surgical outcomes of patients with CLM. Approximately one-third of actual 5-year survivors suffer cancer-related death, whereas patients who survive 10 years appear to be cured of disease.

Abstract
Metastatic colorectal cancer is a particularly frequent and severe cancer. Patients die mainly from metastatic disease; however, the survival of these patients has dramatically improved with the progress in chemotherapeutic regimens as new routes of administration and introduction of more potent cytotoxic agents administered in sequential 5-FU-folinic acid-irinotecan/5-FU-folinic acid-oxaliplatine strategies. Biologic therapies have been also developed targeting two different pathways, angiogenesis and the epidermal growth factor receptor. Their combination with chemotherapy leads to improved progression-free survival and overall survival in some cases as the addition of cetuximab in wild-type K-Ras tumors. The objectives of this expert conference were to review the different options, the available prognostic or predictive factors to optimally guide the treatment.

Abstract
BACKGROUND Long-term outcomes after hepatectomy for colorectal liver metastases in relatively young patients are still unknown. The aim of the current study was to evaluate long-term outcomes in patients < or = 40 years old, and to compare them with patients >40 years old. METHODS All consecutive patients who underwent hepatectomy for colorectal liver metastases at the authors' hospital between 1990 and 2006 were included in the study. Patients < or = 40 years old were compared with all other patients treated during the same period. Overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) rates were determined, and prognostic factors were identified. RESULTS In total, 806 patients underwent hepatectomy for colorectal liver metastases, of whom 56 (7%) were aged < or = 40 years. Among the young patients, more colorectal liver metastases were present at diagnosis, and they were more often diagnosed synchronous with the primary tumor. Five-year OS was 33% in young patients, compared with 51% in older patients (P = .12). Five-year PFS was 2% in young patients, compared with 16% in older patients (P < .001). DFS rates were comparable between the groups (17% vs 23%, P = .10). At multivariate analysis, age < or = 40 years was identified as an independent predictor of poor PFS. CONCLUSIONS In young patients, colorectal liver metastases seem to be more aggressive, with a trend toward lower OS, more disease recurrences, and a significantly shorter PFS after hepatectomy. However, DFS rates were comparable between young and older patients, owing to an aggressive multimodality treatment approach, consisting of chemotherapy and repeat surgery. Therefore, physicians should recognize the poor outcome of colorectal liver metastases in young patients and should consider an aggressive approach to diagnosis and early treatment.
